Description
Technical field
The present invention relates to bituminous concrete mixture mix equipment technical field, be specifically related to a kind of bituminous concrete mixture and mix and stir bitumen aggregate ratio and mineral aggregate grating online automatic detection technology and regeneration asphalt in the process and mix and detect automatically and system that mixture quality is controlled.
Background technology
Highway in China is built particularly, and high-grade highway construction develops very fast; And that asphalt concrete pavement is used in highway construction is very extensive; Hot-mix asphalt mixture is the ground surface material that is widely used in each standard highway; It mixes and stirs quality and programming that quality directly influences asphaltic road-mix surface course, is one of most important operation in the whole asphalt concrete pavement construction operation, and the quality of asphalt concrete pavement is directly related with the match ratio of bituminous mixture.
Developed countries such as Europe, U.S.A, day are all obtaining significant achievement aspect the production technology of reclaimed asphalt mixture and supporting with it various excavations, milling, fragmentation, the development of facility such as mixing and stirring and the exploitation at present; Through nearly 30 years large-scale production practice; Proved that asphalt-regenerating is utilized in technical feasibility; And the complete asphalt-regenerating that has formed system is technological, and has reached standardization and standardized maturity.
Along with the appearance with standard criterion is improved in the continuous development of China's asphalt pavement regeneration application technology; Meet in highway construction that the asphalt pavement regeneration technology of recycling economy pattern will be afterwards, the maintenance project and be more widely used; The introduction of regeneration asphalt Study on Technology, popularization and its relative special-purpose equipment and exploitation are to reducining the construction costs, make rational use of resources, preserve the ecological environment and promoting highway construction that earth shaking meaning is all arranged.
Traditional bitumen content and mineral aggregate grating are to obtain through extraction test method or firing method, or outward appearance and material thick through AIMS system evaluation, fines.The bitumen content check of bituminous mixture is to obtain through extraction test method or firing method in the laboratory, and test period is more than 30 minutes, and general every morning and afternoon do battery of tests respectively and control, and can not analyze immediately the quality of bituminous mixture.The AIMS system estimates outward appearance and material thick, fines through analyzing the image of being captured by camera (black, white, three kinds of forms of ash), and black, white image is used for analyzing its shape and water caltrop property, and the grey image is used to analyze its material.
Because mineral material size is irregular, different, the thickness of pitch parcel is irregular, and the AIMS system can not carry out the three-dimensional statistics to all mineral material particles, and accuracy of quantitative analysis is not high.Because the variability of the bitumen content of old material, mineral aggregate grating is bigger, the quality stability of reclaimed asphalt mixture is a technical bottleneck of restriction large-scale application always.
Mainly there is following problem in traditional bituminous mixture machine: the mode that the asphalt mixture machine of (1) different model, specification, manufacturer injects pitch is different, and control bitumen content precision is also just different, influences the stability of quality of asphalt mixtures.(2) asphalt mixture machine adopts batch (-type) asphalt mixture machine or continuous asphalt mixing machine, because mixing machine machinery, electronic weighting departure, so mineral aggregate, asphalt content produce error.(3) size and the feeding belt running speed unstability of the unlatching of cold burden warehouse discharging mouth can not reach uniform feeding with accurate.(4) the proportioning variation that causes of mineral aggregate water content, the quality of bituminous mixture is unstable.(5) domestic and international batch (-type) asphalt mixture machine or continuous asphalt mixing machine goods producer do not have the bitumen aggregate ratio of design and installation bituminous mixture and the online automatic detection control appliance of mineral aggregate grating.(6) domestic and international bituminous concrete mixing station in bituminous mixture mix process, does not have every biscuit that the bitumen aggregate ratio and the mineral aggregate grating of bituminous mixture are detected.
Mainly there is following problem in existing reclaimed asphalt mixture machine: the variability problem of (1) waste material.The variability of the bitumen content of waste material, ageing of asphalt degree and aggregate grading is generally all bigger, directly influences the quality control of reclaimed asphalt mixture.(2) the batch (-type) asphalt mixture machine is hot in-plant reclaimed, huge owing to complex equipments, technology controlling and process is difficult, cost is high, the regeneration quality with old material fluctuate, old material adding proportion less etc. reason do not obtain practical application at home.(3) the continuous asphalt mixing machine is hot in-plant reclaimed, because equipment is simple relatively, output is big, cost is low, uses the most extensively, but owing to does not have real-time old material Quality Monitoring Control System, reclaimed asphalt mixture quality instability.
Mainly there is following problem in existing bituminous concrete mix detection system: (1) is owing to the reason of equipment and technology condition, engineering quality control system and technological process; Every mixing machine every day 1～2 time; With the average evaluation of 2 samples, can not carry out quality evaluation to the compound of every dish.(2) there is not bituminous concrete mix on-line automatic monitoring system.
Existing reclaimed asphalt mixture is controlled system and mainly had following problem: (1) is owing to the reason of equipment and technology condition and technological process; Can only be that production mix proportion carries out feed according to test; To the compound bitumen aggregate ratio of supply and the variation of mineral aggregate grating, can not carry out real-time supply.(2) there is not reclaimed asphalt mixture feed control system.
